Greetings, Because of the heavy load and the high expectations of an asterisk server offered as a solution integrated with our CRM software.. we were looking into other possibilities than software Licenses for G729 and G723 codecs.. to lower the pressure on the processor giving it more space to do more work. We heard of a hardware (PCI CARDS) can be used with Asterisk that does the work. And we stumbled with Digium TC400B. Could be a newbie's question.. but does that serve our needs? As we have not pressured a server before up to 1400 extensions with 600 outbound SIP calls (customer's needs). The server in question is Core I7 16 GB ram and Raid 10 SAS drives. We need to know how many calls with G729 or G723 can this server handle? And as far as we can see this Digium card can be a cheaper solution If calculating the CPU cost plus the licenses for each channel. One more question.. can we add two of those cards to the server? Will it be efficient? Regards Tarek Sawah

We can resell the Sangoma card. They have some higher license counts as well. They are also offering a step up offering. If you buy at one level and need to move to the next. They will offer you a trade back on the old card.

The driver spreads the load among installed cards.

The new sangoma G729 cards have the ability to do up to 2400 channels per card depending on the configuration purchased. The sangoma option is really good option once you get the 120 channel level. The real question is how many channels do you need to transcode. In certian combinations asterisk can eat g729 channels. Let's say you are coming g729 and recording and then going back out g729 you may eat up to 4 encode/decode license. For some calls if your end points are g729 and your carrier is g729 you many not need any license. It comes down to how many of your calls will need access to non g729 prompts and how many calls will need to be converted due to differing source formats. If you can convert your ivr prompts to g729 you get a win here. But playing voicemail files will never use g729 as it is not currently a supported record format as far as I have found My guss is one of the sangoma 400 license cards would likely meet your needs That will range between $2200 and $2300 A single sangoma 240 license card is between $1550 and $1650 The digium TC400B selles for beteen $1025 and $1200.00 If you want more details you can contact me off list.
